Ten years on: Witnesses recall horror of Glasgow bin lorry crash
Right Reverend Dr Gregor Duncan, the Scottish Episcopal Bishop of Glasgow and Galloway, was also on at the scene in the aftermath of the crash.
Now retired, he told the Press Association he will this weekend pray for the six victims, as well as the driver.
It later emerged Mr Clarke had previously passed out[1] while behind the wheel of a stationary bus but did not tell his employers.
Right Rev Duncan recalled: "That afternoon I went out, and when I went back the road was closed off with lots of people around.
"I saw human remains on the road, some covered, some not.
"I realised something terrible had happened and went back to my office and put my clerical dress on."
The enormity of the tragedy soon dawned on the Bishop.
He said: "Someone said to me out of the crowd 'Five souls, Father' - by which she meant five people had been killed, at that stage, I didn't know how.
"She might have been asking me to pray for them."
Right Rev Duncan said Glasgow felt "stricken" in the aftermath of the crash, which came just a year after 10 people were killed when a police helicopter crashed into the Clutha pub[2], less than a mile away.
He added: "I think Glasgow felt afflicted.
The time of year made it even worse.
"Some tragedies happen out of thin air, but others happen because of human error or human folly."
